What is DID – Direct Inward Dialing?

DID Page-01.png

DID is a feature offered by telephone companies for use with their customers’ PBX system, whereby the telephone company (telco) allocates a range of telephone numbers associated with one or more phone lines. DID allows a company to assign a personal number to each employee, without requiring a separate physical phone line, for each, to connect to the PBX. This way, telephony traffic can be split up and managed more easily.
